Megapoxy 254 is a white, non-sag epoxy adhesive paste for bonding and repairing concrete, metal, brick, fibre cement, ceramics and natural stone. Its thick, creamy consistency stays in place on vertical and overhead surfaces, while the non-staining formulation makes it useful for white marble and other light-coloured stone.
Use 254 for precast concrete bonding, damaged stair and column repairs, bolt grouting, bonding metal to concrete and filling defects in concrete pipes or tanks. The white finish is a practical advantage when repairing pale stone or ceramics close to a visible edge.
These two non-sag epoxies overlap in many construction repairs and both have a 45-minute working time at 25°C. Choose 254 when you need the white formulation supplied here in a 20 L kit. Megapoxy PM is also available in smaller kits, white or grey, plus a grey DuoMix cartridge. For urgent small repairs, Megapoxy PF sets considerably faster.
Before bonding: Remove loose concrete, laitance, grease and coatings from the bonding faces. Mix equal volumes of A and B until uniform, then apply within 45 minutes at 25°C. Do not use below 10°C or above its 70°C maximum operating temperature.
What is Megapoxy 254 best used for?
Vertical and overhead structural bonding, concrete repairs and bonding light-coloured stone.
Will it sag on a wall?
Its paste consistency is formulated to remain in place on vertical and overhead joints.
Can it bond marble?
Yes. The white, non-staining formula suits light-coloured marble and other natural stone.
What is its working time?
Approximately 45 minutes at 25°C, with a minimum cure of 24 hours at that temperature.
